Long Term Annual Water Balance
Evaluate the long-term water balance for four rivers around the
world.
| Iowa River at Wapello | Amazon River Brazil |
Yangtzekiang River China | Ob River Russia |
Watershed area (km2) |
32,372 | 7,180,000 | 1,970,000 | 2,950,000 |
Precipitation (mm/yr) |
838 | 1777 | 1120 | 563 |
Streamflow (cms) |
227 | 190,000 | 35,000 | 12,500 |
- Compute the mean annual evapotranspiration (in mm/yr).
- Compute the runoff coefficient (annual river discharge as a fraction of precipitation) (in %).
